Ranking the Most Dominant Calendar Years in Boxing History

This list had to be dominated by the old-timers. In earlier eras, even world champions often fought multiple times per month.

While Henry Armstrong certainly beat his share of club-level fighters en route to going 27-0 with 20 KOs in 1937, he also beat a number of top contenders and collected the world title at featherweight from Petey Sarron.

Great fighters also had to fight one another more often in those decades. Fighting a bunch of times per year, with multiple bouts against fellow top stars, it was rare for a fighter to truly dominate for even an entire calendar year.

Even with the monumental achievements of Boxrec, records for some early stars can be less than complete. In some cases, the decisions are even disputed between different newspapers.

10. Mike Tyson, 1986

Mike Tyson is the only modern fighter to make his way onto this list. That explains a large part of his enduring mystique. When Iron Mike broke onto the international scene as a teenager in the mid-1980s, he was a true throwback fighter. 

Tyson fought at an extremely busy rate while rapidly climbing to the top of the heavyweight food chain. In 1986, he posted a 13-0 record with 11 KOs while also becoming the youngest heavyweight champion in history.

Tyson still wasn't old enough to legally drink and was knocking out solid journeymen fighters like Jesse Ferguson and James Tillis, as well as fellow rising contenders like Mitch Green and Marvin Frazier. He capped off the year in November by stopping Trevor Berbick in two rounds to claim the WBC heavyweight belt. 

9. Jack Dempsey, 1918

Jack Dempsey ruled for most of the 1920s as the heavyweight champion and as one of the biggest stars in America in any field of endeavor. He captured the belt in 1919 by handing Jess Willard one of the worst beatings in heavyweight history. 

But 1918 was the year when Dempsey exploded as a major attraction and turned himself into the obvious No. 1 contender for the big belt. The Manassa Mauler went 19-1-1 with 17 KOs for the year.

Dempsey drew with Billy Miske in May 1918, but won by dominant decision six months later. He also gave Battling Levinsky the first knockout loss of the Hall of Famer's career.

8. Joe Louis, 1935

The longest-reigning heavyweight champion in history, Joe Louis had his most dominant year overall prior to actually capturing the belt. In 1935, he emerged as a young phenom at heavyweight. 

That was the year he served notice that he was the future of the division. For the year, Louis went 11-0 with nine stoppages while moving up to the top of the divisional rankings. 

In addition to beating a tough collection of journeymen, such as King Levinsky, Louis knocked out former world champions Primo Carnera and Max Baer in 1935. Louis would suffer a shocking setback in 1936 against former champion Max Schmeling but would go on to capture the title in 1937, and then knock out Schmeling in the 1938 rematch.  

7. Harry Greb, 1922

Harry Greb fought just 12 times in 1922, which for him was nearly retired compared to his work pace from only a few years prior. Still, he remained near the top of his craft and won some major big fights against legends. 

Boxrec lists Greb as going 12-0 for the year. He recorded wins over tough veteran Jeff Smith and against light heavyweight great Tommy Loughran. 

During 1922, Greb also gave Hall of Famer Tommy Gibbons the first loss of Gibbons' career and the legendary Gene Tunney his only career loss. 

6. Joe Gans, 1902

Joe Gans should probably come up with more regularity when people on social media start throwing around candidates for the top 10 of all time. The footage that is easily available of this pioneer shows a fighter who clearly had a scientific understanding of distance, angles and disruption. 

Gans fought in an era when fighters had to travel the rails like musicians, fighting from city to city and sometimes fighting over and over during a month. The borderline legality of boxing at the time also created a legacy where victors are not always easy to gleam from the historical records, as competing newspapers sometimes recognized competing claims. 

Still, the surviving evidence for the greatness of The Old Master is not debatable. He was viewed as a giant by, and among, his contemporary peers. 

On his Boxrec resume, Gans appears to have been particularly outstanding in 1902, when he went 18-0 and knocked out 14 opponents. He captured the World Lightweight Championship by stopping Frank Erne in Round 1 that May. Among his other wins in 1902 were two over the infamously dirty George "Elbows" McFadden and one over Kid McPart. 

5. Henry Armstrong, 1937

In 1937, Henry Armstrong had the first year of what must be regarded as the best two-year run in the history of the sport. The level of dominance Homicide Hank achieved in 1937 and 1938 has never been equaled since and never will be. 

Over the course of 1937 and 1938, Armstrong had a streak of 27 consecutive knockouts. He went 41-0 over the two years combined, with 30 knockouts, and won three of the eight existing world titles.

In 1937, Armstrong was 27-0 with 20 KOs. In October of that year, he won the featherweight title from Petey Sarron by Round 6 KO. 

4. Sugar Ray Robinson, 1942

If I were to pick the most dominant decade for a boxing career, I would give it to Sugar Ray Robinson for 1942 through 1951, with 1952 being a pretty strong outlier on the final end. Nobody else in the sport's history has a 10-year stretch in which he fought as frequently and as dominantly against the sport's best.

In 1942, Robinson was still a young fighter who was building his remarkable legacy, so it's not a surprise that activity level makes that year arguably the top of his run. He was still being denied a shot at the title in 1942, but there was no doubt that he was the top fighter in the world. 

He went 14-0 for the year, with nine stoppages. He beat fellow Hall of Famers Marty Servo, Jake LaMotta, Fritzie Zivic and Sammy Angott, along with contenders Maxie Berger and Al Nettlow.  

3. Benny Leonard, 1917

Known as "The Ghetto Wizard," Benny Leonard was a brilliant technical fighter who reigned as lightweight champion from 1917 until his first retirement in 1924, at age 28. In 1917, he was at his busiest while beating some high-level opponents. 

For the year, Leonard was 28-0. In May, he captured the lightweight title by Round 9 TKO over Freddie Welsh, knocking the well-traveled champion down three times. 

In 1917, Leonard also beat Jack Britton and Johnny Kilbane, the two great champions of that era in the weight classes above and below Leonard. 

2. Harry Greb, 1919

Harry Greb's 1919 campaign defies belief. According to the Boxrec records, the Pittsburgh Windmill went 45-0 for the year. 

Plenty of the names on Greb's resume that year were forgettable club fighters, but they were all professionals who were trying to take his block off and earn a sudden reputation. Simply sparring hard that often over a year, with trusted training partners, would be a brutal pace to sustain.

And Greb was fighting big names when he could get them. He beat reigning light heavyweight champion Battling Levinsky three times in 1919. He beat contenders Mike Gibbons, Willie Meehan and Billy Miske. He beat respectable journeyman Leo Houck twice. 

In today's era, compiling three wins over a world champion, three more over tough contenders and another two over a good journeyman in a single year would be viewed as unprecedented. 

In 1919, Greb did that, plus he won another 37 professional fights. 

1. Henry Armstrong, 1938

Henry Armstrong entered 1938 as the reigning world champion at featherweight. Before that year ended, he collected the welterweight and lightweight titles as well. 

At a time when there was only one champion per weight class and only eight weight classes overall, Homicide Hank held three belts at the same time. As many as 20 or more "champions" might reign over that same span of pounds in today's version of the sport.

For the year, Armstrong maintained a pace of fighting more than once per month, going 14-0 with 10 stoppages. He also recorded wins over fellow Hall of Famers Baby Arizmendi, Chalky Wright, Ceferino Garcia, Lou Ambers and Barney Ross.
